The present disclosure provides a method of controlling driving of a vehicle by estimating a road frictional coefficient, the method including distributing torque to a front wheel and a rear wheel to satisfy required torque for driving, by a controller, in a four-wheel drive (4WD) vehicle including a front wheel driving device and a rear wheel driving device installed therein, and performing torque excitation control for increasing torque applied to one of the front wheel and the rear wheel to which the torque is distributed while the vehicle is driven, and simultaneously, changing torque applied to a remaining one of the front wheel and the rear wheel in such a way that the sum of front wheel torque and rear wheel torque satisfies required torque, by the controller.
